Yup...sounds like Asterina sp to me. They intitaially appear harmless,
however many of the species of this genus will munch on your SPSs. Get them
out now. I tried a watch and wait approach, suddenly the population
exploded and that is when they started munching on my Acropora

Over the past couple of weeks, we have had two small (half inch across)
what looks like starfish appear int he tank. Each is similar in that
they are greenish white with three "proper" legs and three or four
"stumps". The are currently clinging to the glass on the side of the
tank.

The look soft with soft serrated edges.

Any ideas?
